★ "1 to 100" Number Concept + Social-Emotional Learning Picture Book: One hundred friends with distinct personalities and outfits gather for a pajama party, presenting a warm vision of inclusion, sharing, and coexistence.
★ One hundred uniquely charming friends — one in potato-print pajamas, another snacking on worm jelly, others mid-pillow-fight... The illustrations hide countless details and clues leading to a twist ending. Children discover something new with every reading, building observation skills and sustained focus.
★ What seems "scary" transforms into warmth — the vast cave is no longer a lonely hiding place, but a home of shared joy with friends. The story teaches children: even the largest space feels empty when you're alone; even the smallest corner feels lively with friends.

What if there were a bed so giant that 100 friends could lie on it at once? A chaotic pajama party unfolds as animal friends tuck themselves in under blankets numbered 1 to 100. Friends chatting the night away, friends stuffing their cheeks with bunny-paw pie, carrot cookies, and chestnut bread, friends bouncing on the fluffy bed, and friends having pillow fights! As quiz time comes to an end, they pull blankets over their faces and start telling spooky stories until a scream startles everyone... On this giant bed, how will Squeaky and the friends’ pajama party finally come to an end?

He studied computer engineering at university and worked as a computer engineer. At some point, stories he longed to share with children began filling his mind. To tell these stories through engaging words and pictures, he left his job — though creating picture books proved far more challenging than imagined. He studied and struggled for a long time. He still loves picture books deeply, writing and drawing every day.
